Biology

Jolteon is a quadruped, mammalian Pokémon. It is covered in yellow fur with a spiky fringe around its tail, and a white ruff around its neck. In addition to the ability to become sharp like needles, Jolteon's fur also amplifies the electrical charges produced by its cells. It can also store and generate negative ions in its fur, which create a sparking noise. Its ears are large and pointed, and its eyes and small nose are black. It has slender legs and small paws, each with three toes and a pink paw pad. This Pokémon is most often found in cities and towns under the ownership of Trainers.

Red's Jolteon

In the manga

In the Pokémon Adventures manga

In Blame it on Eevee, Red temporarily controlled a Jolteon, which was actually his mutated Eevee switching between its evolved forms. Eventually, it lost the ability to devolve after permanently becoming an Espeon, but Red felt more content now that it'd been freed from the pain that Team Rocket's experiments had dealt.

A Jolteon appeared when Yellow fantasized about Pokémon that could evolve via stone along with an Eevee, Vaporeon and Flareon in The Kindest Tentacruel.

Jolteon's cells generate a low level of electricity. This power is amplified by the static electricity of its fur, enabling the Pokémon to drop thunderbolts. The bristling fur is made of electrically charged needles.

Trivia

Jolteon shares its species name with Electrike. They are both known as the Lightning Pokémon.

Jolteon and Zapdos's Japanese names (サンダース Thunders and サンダー Thunder, respectively) are almost exactly the same as each others', with a final s being the only difference.

Origin

Its physical anatomy seems to be primarily based on a herding dog or possibly a fennec fox, with several traits of coyotes. It is also feline-like; its extremely high speed resembles that of a cheetah's. It may also be inspired by the raijū, a beast from Japanese mythology whose body is made of thunder, and may take the form of a cat.

Name origin

Jolteon is a combination of jolt and eon (an immeasurably long period of time, possibly referring to how long evolution takes naturally). Eon is a suffix all Eeveeevolutions share and was Eevee's English prototype name.

Thunders is literally thunders (present tense of the verb to thunder).
